SILICONE AND SILOXANE-BASED IMPREGNATED COATING AND POLYMERIC MATERIALS FOR CONDITIONING
The present disclosure generally relates to a personal care device comprising an immiscible conditioning composition formed by combining a hydrophilic matrix, such as a polymeric material, and a hydrophobic conditioning agent. More particularly, the present disclosure relates to a personal care device comprising a hydrophilic matrix, such as a polymeric material, and a hydrophobic conditioning agent dispersed therein, such as a silicone or a siloxane-based agent suitable for transferring from the device surface, and more particularly the matrix surface, to hair or skin surfaces in contact therewith.
1 - 24 . (canceled)
25 . A method for making a personal care device comprising a component having a contact surface, the contact surface component comprising a solid matrix of a porous, hydrophilic material and a hydrophobic conditioning agent fluid dispersed in the pores of the solid matrix, the method comprising:
forming an immiscible composition comprising a hydrophobic conditioning agent fluid and a hydrophilic material;
extruding the immiscible composition to form a personal care device; and, cooling the extruded device;
wherein extrusion and cooling are carried out under conditions sufficient for the hydrophilic material to form a porous solid matrix having the hydrophobic conditioning agent fluid disperse therein.
26 . A method for coating a personal care device with a conditioning layer for contacting a hair or skin surface, the conditioning layer comprising a solid matrix of a porous, hydrophilic material and a hydrophobic conditioning agent fluid dispersed in the pores of the solid matrix, the method comprising:
preparing an immiscible composition comprising a hydrophobic conditioning agent fluid and a hydrophilic material;
forming the immiscible composition into a layer by a sol-gel process, wherein the hydrophilic polymeric material is a porous solid matrix having the hydrophobic conditioning agent fluid dispersed in the pores thereof; and,
applying the layer to a surface of a component the personal care device.
